[0002] Due to the continuous expansion of urbanization in my country, construction is basically carried out in the main urban areas and their surrounding areas. In the process of construction, it is inevitable that dust pollution will be caused to the surrounding environment. At this time, dust removal spray devices will be used to remove dust from the construction site.
